A subclass of DefaultTableCellRenderer that
implements UIResource.
DefaultTableCellRenderer doesn't implement
UIResource
directly so that applications can safely override the
cellRenderer property with
DefaultTableCellRenderer subclasses.

Warning:
Serialized objects of this class will not be compatible with
future Swing releases. The current serialization support is
appropriate for short term storage or RMI between applications running
the same version of Swing. As of 1.4, support for long term storage
of all JavaBeans™
has been added to the java.beans package.
